@Duallight I did see the polarity, but the broken circle is still pointing to the + on both plugs, so I thought that was same polarity but the symbol is just different for some reason, are they definitely opposite?
Hello! I have a device (LED strip) that I'd like to substitute an adapter for. The first adapter (pic 1) isn't long enough, so I'd like to sub it with adapter 2 (pic 2). I think this is all OK, but I pulled adapter 2 out of a box of cables I had in my parents' house and I just want to be sure before I plug anything in. [Pics](https://imgur.com/a/x80XhzV) Thanks!

@nyarlathotep thank you so much! There's other comments to read below, but this is the first one that has triggered my memory for common denominators. You've explained it brilliantly!
Edit: can you explain how the reciprocal works and comes out to 2/9? Been a long time since high school
Hi, can you help me with a math problem kbin? It's algebra, and it's been a long time since I've had to do it. Can you explain to me how simplifying the terms comes out to 9/2 in the pictured equation please? [\#AskKbin](https://kbin.social/tag/AskKbin)
